How to modify the CEdit control's right-click menu

Introduction

Have you ever wanted to modify ' context menu of ' an ' edit control? The would start by overriding the Oninitmenupopup () function is only "find", "Edit control" does not post a wm_initmen Upopup message, so your function is never called. It's a simple CEdit derived class. The Cmenuedit class

The Cmenuedit class does its job with just two functions, OnContextMenu () and OnCommand ().

The OnContextMenu () function gets called when a user right-clicks on the edit control. In our override, we create a new popup menu which exactly duplicates the default context menu, and we call TrackPopupMenu () On that menu. By doing this, the a WM_INITMENUPOPUP message was posted, which can then be handled to a class derived from Cmenuedit.

The OnCommand () function handles commands generated when a user selects an item from the menu. If the command isn't generated by we menu, it is passed onto Cedit::oncommand ().

You can either derive your edit class from Cmenuedit or include this two functions in your class. Updates
